Year!!!! Looks like you've caught A BIG FAT RAT!!! One of the BIGGEST!!!
I'm a person responsible for all java-based-serving on our sites, not very
loaded yet.. And looks like _this_ is the problem that has nearly given
me _grey_ hair!!!

(What i ended up developing is a pinging facility that would find if our
nice good Tomcat is _DEAD_ and force-restart it!!!)

Can this happen to Ajp12 connections also? Please, anybody! this is the main 
question that i'd like to find out: our Tomcat falls tead pretty often (guess what
my bosses tell me when our sites stop responding!!!) and we do not know why..
The thing is that although we have built-in Web server set (http connectors) up 
for all Tomcat instances (we still have 3.2b7..), they are not practically used 
much (maybe not invoked at all).. They are used via Ajp12. Can this same thing
happen in this configuration (with mod_jserv on Apache, Apache running on BSD,
Tomcat on Linux RH 6.2)

Most hearty greeting to evryone,
sincerely yours, Tagunov Anthony
